Application filed: May 31,

ToaZZ whom it may concern: I

Be it' known that I, Gnoncn NOPOL'ION THERRIEN, a citizen of the United States, residing at Keene, in thecounty of Cheshire and'St-ate of New Hampshire, have invented new and useful Improvements in Spike- Driving Machines, of which the following 1s a specification.

My present'inventionhas' reference to a machine: for spiking rails to ties.

Theimprovement is in the'nature ofa respiking jmachi nepthat is a machine designed fordriving home loose spikes, and the primary object of the invention is to produce a'machine for this purpose which will be automatic inaction.

A furtherrobject is toproduce-a-machine for drivinghome loose spikes in thesupporting-tiesfor'railway rails that is mounted on a truckwhichtravelson the rails and that is provided'witlia feelermember for contact ingithespikes ononeof the sides of the rails which actua'tes driving" means in the nature of a hammer'that forcibly cont-acts with-the spikes on each side of therails for effectively driving such spikes home.

p A still further object is to produce a re spikingdevice in which a t'e'eler member is disposed in advance of normally elevatedspringinfliienced hammers andwhich after contacting-with a spikeon one ofthe sides of the-rails will actuatemeans for releasing the hammer to causevthe same toforcibly contact and drive home the spikes on both sides of the rails',,n1ea'ns being'providedfor holding'the feelerlmember out of the path of engagement with" the hammer previously to 'and immediately' after the engagen'lent of the hammer with the: spikes, means being provided for: returning the hammer to its in itia'l position and thereafterreturning. the 'l'eeler to active position whereby the same willbebroughtinto the path of contact with the next spike on the. succeeding tie, and

again cause the operation of the hammer, all of'such' means beinggantomatic in action.

The foregoing,- and many other objects which will present themselves as the nature of the invention is better understood, may be accomplished by' a. construction, combination and operative association of elements such 7 1111 of Figure specificationof Lettersratent. Patgnt d A 11 22 1921. SriaLNo. 473,672.

asiis disclosed by the drawings which acc'ompany and whlch form part of this application. The'nature of the invention is such as to render the same susceptible to various changes in'size', form, proportion and other detailsoficonstruction, all of which, how-' ever, falhng within the scope of what is on 61-6 of Figure l. i

Figure" 7- is a sectional view on" the line 7 -7 of Figure 1 and showing the mannerin on' the line" are he on" the i which t-he'spike contacting or feeler member is'held' inactive until after the hammer has been returnedto its initial'elcvated position.

Figure Sis a sectional view on the line Figure 9 is a fragmentary cle\-'ation,with the shaft 37 in section, and showingthe ratchet wheel'th'ereon; engaged the, pawl which is pivotally supported on" one of the members of the frame.

I Figure lO'is a plan view showing'the 'teeler member about tocngage a spike, the" shaft for'the feeler member being. in section.

- Figure 11 is a'sectionaliview on the line In the drawings, track are indicated-by the numeral 1, the

supporting tiesifor the rails by the numeral 2, and the spikes which see ties by the numeral w p 7 p i 'In the present method, as far as. I am aware, rallroa'd concernsemploy traclrwalkure thei'ails to the the rails of a railway ers for tightening loosejbolts onrailjoints and for ClIlVlIlgllOlllGlOOSQ'SPlkGS. Because v of the vibration to'iwhichthe rails are subjected and also-because of splitsor crevices in the ties, the spikes are comparatively easily loosened from engagement with the rails, andLbecauSe otthis many accidents have occurred. It will be apparent, as the description progresses that with my improvement every spike, whether loosened or not, will be contacted by the hammer of the device, the loosened spikes driven home, and the spikes not materially loosened more effectively forced into engagement with the rails.

As disclosed by the drawings, I make use of a truck 1 which may be of any desired size and proportion, and may be and preferably is, of the ordinary construction in common use on rails. The truck may be hand propelled or may be of the type that is manually moved along the track. In the showing of the drawings I have illustrated the truck provided at one end with a frame extension, the said frame projecting over one of the rails 1. It will be apparent, and it is to be understood that the truck may be constructed to include this frame, and also that the mechanism supported. on the frame over one of the rails maybe duplicated, and arranged over the other rail.

The frame, has 'journaledat its forward end the axle of a wheel 6 which travels on one of the rails 1 and which supports the forward end of the frame. The frame includes longitudinally spaced members 7 and transverse members 8 connecting the said longitudinal members. To the rear of the wheel 6 I bolt to the inner confronting faces of the longitudinal members 7 a substantially U-shaped housing 9. The housing is wholly constructed of metal, and has its parallel side members hollow for the major length thereof to provide substantially rectangular pockets 10. The pockets are open at the top of the housing, and the inner or confronting walls of the side members 11 that are provided with the pockets have central openings 12 therethrough, the said open ings being of a length equalling that of the pockets. The side members 11, at their upper corners have outstanding lips 13 to receive therebeneath the inturned lips 14 formed on the flanged ends 15 of cover plates 16. "The lower or connecting wall 17 for the sides of the housing 9 is provided with a pair of spaced vertically disposed substantially rectangular openings 19 and a centrally arranged transverse round opening 20 between the openings 19. Depending from the under face of the horizontal wall of the casting which I have referred to as the housing is a lug 21 of a width greater than that of the head of the rail 1 which it overlies. The lug has its lower end bifurcated, and the spaced arms 22, thus pro-' vided, are disposed to the opposite sides of the head of the rail 1, but are out of contact with the said head of the rail. Journaled in suitable bearing openings in the arms 22 is the shaft 23 for aroller 24, the said. roller riding on the head of the rail 1. If desired,

the shaft 23 may be influenced by suitable spring means for holding the roller against the tread surface of the rail.

Two hammer members are employed, each of a similar construction. The hammer members are formed of suitable metal and are each substantially rectangular in cross section. Each hammer member is indicated by the numeral 25 and is received through the respective openings 19 in the lower wall of the casting providing the housing 9. The portion of each of the hammer members 25 projecting above the lower wall of the housing is formed with a substantially rectangular extension or widened portion 26 at the diagonally opposed inner corners orfaces of the respective hammer members These rectangular enlargements are disposed side to side and maybe in contacting engage .ment with each other. As a matter of fact, the hammer may be constructed from a single element to provide the upper widened or body portion on the sides or legs that pass through the openings 19. Each of the hammer members, at the portion thereof disposed above the lower wall of the housing 9 has an angle finger 27 that is received through the respective openings 12 on the sides 11 of the housing 9. The upper face of each of the fingers is flat and has resting thereon a plate 28. If desired the plates may be secured to the fingers. On the plates 28 rest strong helical springs 29. The upper ends of these springs bear against plates 30. Each ofthe cover plateslG has its outer face centrally enlarged by'a boss providing a threaded opening and in each of these openings there is the threaded shank 31 of a headed bolt member 32. By adjusting the bolts. the tension of the springs will be regulated. The springs, together with, the weight of the hammers are at all times suflicient to forcibly move the hammers downwardly into contacting engagement with the spikes on the opposite sides of the rail 1, and the width of the hammers equals or is slightly in excess of the width of the ties 2 in which the spikes 3 are driven.

On the upper face of the wall 17 of the casting 9 there is a yieldable buffer 33 against which the lower edges of the widenedv upper portions ofv the hammer members contact when the same are influenced by their r ara aaa respectively: Qfrthe sides ofthe Widenedf upper portions of the'hammer-members are stub shait's or lugs'40'. @n ea-chrof'the stubsha-fts 40 there-is a roller-fla The stub shaftsare directed toward the respective: cam

wheel's-38 and 39; so that the rollers 41 there of are engaged by thecam surfaces of: the said Wheels when the shaft 37 is moved* to that is secured thereon and that is engaged b a pawl 431tl1atr is pivoted to one-of the transversemembers 810i? the frame; The purpose of the pawland ratcheti is to' hold the shaft. tronrturning bythe pressure exerted on thevcam: wheels38 and 39 by the weighted hammer members and: the springs that influence the said i hammers.

On either the frameor the truck there is a motor 44: Iffdesired'. thismotormay' provide means: for propelling thetruck; The shaft or" the motor has secured thereon a gear wheel J451which is in mesh rwith'a pinion 46-that is loose on the shaft 37. The pinion 4:61 is held againsfllongitudinal: movement on! the shaft 37' byv means on: the opposite sidethereof indicated by the numeral 47. The pinionu oniits outer-"face. or the face thereof confronting the hammer and casting 9 is providedwith or has secured thereon atoothediclutohlwheel 48. The shaft 37 .has its: sides. outward of the clutch wheel groovedto provide seats t'or keys or feathers 49 that: are received: in grooves 50 in the bore 'ofia clutch wheel '51; The clutch wheel '51 is influenced by: springs 52scarr ied byaa.

On theslidable clutc lrwheel or member 48=there is integrally formeda lug; 81. A dog supportingyoke "'82 is supportedion the framerfi; thei dog; which; is pivoted; therein is indicated by the numeral 83. The dog has its inner end provided on one of its corners with a curved lip extension 8% that underlies the clutch member at and that contacts with the lug 81. thereon for holding the clutch member 51 out of engagement with the fixed clutch member $8. The opposite or outer end of the dog is weighted. and is provided on the corner thereof opposite that formed with the lip, with. a reduced e);- tension 85. In the space provided between the end of the dog and the said extension 85 the angle end 78 0t thc'arm it is received, the Ushaped spring influenced contact member carried by the said arm underlying the extension 85. In reality, the extension providcs the tail of the dog.

At the front of the frame. forward of the hammers there are depending shafts 86 that carry at their lower ends wire brushes 87. The brushes are flexible, and contacting with the upper surface of the ties remove stones, gravel or other substances therefrom. The shaft 37, when in inactive positions, sustains the cams 38 and 39 in a position whereby the hammers are retained at their highest elevation. The feeler member will contact with the head of a spike on one side of the rail,and by virtue of such contact the said member will be turned to revolve both the vertical shaft 57 and the horizontal shaft 67. The turning of the shaft 67 will cause the striker member 70 to swing the arm 7% on its pivot. bringing the U-shaped striker member against the tail of the dog, swinging the dog to bring its lip out of engagement with the lug 81 on the slidable clutch 51, permitting the springs 52 to movethe slidable clutch member in engagement with the fixed clutch member 48, thus turning the shaft. By reason of the U- shaped striker on the arm 74:. and its pivotal connection with the said arm the shaft 37 will be permitted one complete revolution to allow the hammer members to be influenced by their springs and by their'weight to spike contacting engagement and to be elevated from such engagement to their initial position, On such turning of the shaft the lip 84 of the dog 83 will again engage with the lug 81 on the slidableclutch member 51, retracting the said member 51 away from engagement with the fixed clutch member 48, the tail of the dog engaging with the U- shaped contact member of thearm 74- swings the arm to its initial position which iuiluences the cam or striker member 70 on the horizontal shaft 67 to turn the said shaft in a reverse direction which, by the intermeshing of the gear thereon with the gear on the vertical shaft will turn the vertical shaft to bring the feeler member to its initial position whereby the said feeler member will contact with the head of the spike on the will thus be seen that the apparatus is automatic inaction. The heads of the hammers, as previously stated, are of a length whereby the spikes on both sides of the rails will be positively contacted with. The construction is simple and may be, as stated, attached to any ordinary railway hand car or truck.
